Kensington SlimBlade™ Pro Wireless Trackball, Rechargeable Battery, Bluetooth 2.4GHz Connection Options (K72080WW)

In a world dominated by standard mice, the Kensington Trackball Mouse offers a refreshing — and highly functional — alternative. Designed for users seeking precision, comfort, and space efficiency, Kensington’s line of trackball mice (particularly the Expert Mouse and SlimBlade models) has earned a strong reputation among graphic designers, video editors, accessibility users, and anyone looking to reduce wrist strain. After several weeks of use, I can confidently say this mouse is more than a niche tool — it’s a productivity powerhouse.Ergonomic Design & ComfortThe most immediate difference is how you interact with the device. Unlike a traditional mouse, the Kensington trackball stays stationary. You control the cursor by rolling the ball with your fingers or palm. This design is a huge win for ergonomics — it eliminates constant wrist and arm movement, reducing the risk of repetitive strain injuries (RSIs), especially during long work sessions.The included wrist rest (on models like the Expert Mouse) adds another layer of comfort. It’s soft, detachable, and encourages a neutral hand posture. Over extended use, I noticed significantly less tension in my forearm and shoulder compared to using a regular mouse.Precision & ControlThe large, smooth-rolling ball is surprisingly accurate. Once you get used to the motion (which takes about a day or two), fine control becomes second nature. Whether you’re navigating through spreadsheets, editing photos, or simply browsing the web, the trackball allows for quick, pixel-level precision — especially useful for design work.Customizability is another standout. The KensingtonWorks software lets you program each of the buttons (typically four on the Expert Mouse) to suit your workflow — from copy/paste shortcuts to opening apps or executing macros. Scroll ring functionality is also intuitive and surprisingly satisfying. Rotating the ring around the ball allows for fluid, smooth scrolling that quickly becomes second nature.Build Quality & DurabilityKensington devices are built like tanks. The materials feel premium, with a sturdy plastic body, high-quality ball bearings, and tactile buttons that hold up well under daily use. Unlike many traditional mice that begin to degrade after a year or two, a Kensington trackball can last years with minimal maintenance — just an occasional cleaning of the ball and socket.Learning CurveThere is a brief adjustment period if you’ve never used a trackball before. It may feel awkward initially, but within a few days, most users adapt quickly. The payoff is worth it — less movement, better posture, and surprisingly faster navigation once you’re accustomed to the motion.Final ThoughtsThe Kensington Trackball Mouse isn’t just an alternative pointing device — it’s a serious upgrade in terms of comfort, control, and customization. Whether you're managing multi-monitor setups, working long hours at a desk, or dealing with wrist issues, this mouse delivers reliable performance with thoughtful design.Rating: 5/5 – Ergonomic, precise, and built to last. An excellent investment for professionals and power users alike.

I use a computer for 12 hours a day and this has saved my wrist. My hands are 16cm long and these are a good size. The buttons are customizable and the scrolling is smooth (with a satisfying click). I still use a real mouse for gaming but this is perfect for work and browsing.

I have used Kensington trackballs for decades. This one is definitely a step up. Lower profile. Smoother action. Overall, very nice. The only criticism is that, when the glides get dirty it can get squeaky. Not loud, but enough to notice. Cleaning the ball and carrier resolves this. Occasionally wiping the ball on your face also help. It puts the tiniest amount of oils on the ball which also eliminates any squeaking.There is no scroll ring. Instead, you rotate the ball by placing a finger on the side of the ball. It sounds strange, but it actually works quite will and is intuitive if you have used an older ball.Overall, a solid improvement from the traditional Kensington design.

Phenomenal! There’s a short learning curve, but from day one, it felt smoother, more comfortable, and more precise than anything I’ve used before. The white and silver design looks stunning on the desk, and once you dial in the right DPI setting, the control feels natural and refined. Build quality is excellent — it’s a premium experience all around.

Trackball user for last 20 years here. This is likely the best one currently on the market. I had a problem with one of the buttons sticking so I got a replacement and the new one works perfectly. I don't even mind having to clean the inside nubs with alcohol and Q-Tips every other day in order to maintain pointer precision.

I bought the first version of this and had issues with it (reviewed on amazon if you want to go looking). This looked like a substantial update internally keeping the great looks of the original.After using it for a few days I didn't like it as much as my Elecom Huge for a few reasons:- I couldn't find a sensitivity setting that both gave me the precision i preferred with the speed that would let me navigate my large multi-monitor setup- I couldn't find a comfortable position and my fingers were cramping- Only 4 buttons and I couldn't get the combo buttons to work properly. (I'd gotten used to 7 plus a separate wheel with the Huge).Bottom line, if you like the classic 4 button symmetrical big Kensington layout, this mouse will scratch your itch. Otherwise the Elecom Huge is more comfortable, is more precise, has more buttons, and a real scroll wheel.
